For each control measure, the Legionella water management plan should include which of the following?

The inclusion of control limits in a Legionella water management plan is crucial for effective monitoring and management of potential risks associated with Legionella growth in water systems. Control limits serve as predefined thresholds for temperature, water quality, and other critical factors that influence the proliferation of Legionella bacteria. By establishing these limits, facilities can determine when conditions are outside acceptable ranges, prompting necessary actions to mitigate risks before they escalate into a public health concern.

Control limits also facilitate the ongoing evaluation of the effectiveness of current water management strategies and allow for timely adjustments. For instance, if the water temperature exceeds a specific control limit conducive to bacterial growth, remedial measures can be implemented immediately to correct the problem. This proactive approach helps safeguard public health and ensures compliance with regulatory requirements concerning water safety.

In comparison, the other options, while they may have relevance in broader management contexts, do not specifically align with the critical elements required for maintaining an effective Legionella water management plan.
